The present invention relates to devices for operating easement or hinged windows and the like. One object of theinvention amongst others is to provide an efficient' device which is of comparatively simple construction and easy to operate.

The improved operating means hereinafter described belongs to the class of devices having transmission means which are operative from a stationary point to throw or adjust and hold the window into the desired open or closed position. Heretofore, various types of devices have been proposed and in many instances the devices are separately designed and constructed :for windows which swing to the right or tothe left as the case may be. Other devices have been proposed where the devices may be changed by're-arrangement of parts so that the same dev1ce cansbe used forw windows swingingA in different directions. According to the present invention the device is improved in general construct-ion and it is v so designed that the same device may be applied to different Windows without re-ar rangement or reversing of the operative parts l of the device.

An embodiment of the invention l.will be described hereinafter with reference to the accompanying drawings wherein- Figure 1 is a perspective view showingthe improved device used in a pair and applied to double windows swingmg in oppositel directions;

Figurel2 is a side elevation of the improved device;

' Figure 3 is la longitudinal section; s

Figure 4 1s a top plan view with the upper cover of the deviceA removed;

Figure 5 is a top plan view ofthe complete -40 device and 'illustrates a form 'of extensible operatin crank which is specially designed foruse or the present improved device.

Referring to said drawings, in Figure 1 the invention is shown applied to double easement Figure windows, the window 1 swinging in an oppo.

site direction to the window 2 and for each window a similar operatin device A is used. This device comprises the ase 3 supporting the pivoted arm 4. An inner member or ro 5 is adapted to slide or telescope within the hollow arm 4 and .at the end of this rod 5 a bracket 6 'is pivotally connected by the pivot 7 tosaid rod.- It will be understood that kthe improved' device can be set up for'operation l for windows operating Ain either a right hand br left hand direction by locating the base 1n Adlerentpositions and b swinging the bracket 6 from oneside o the arm 4 to the other side as r uired. 60 In the embodiment of the invention shown 1n the drawings, the base of the device is composed of an upper section 8 and a lower section .or base plate 9. These two sections are united together b screw 10 and other screws engaged in ho es 10. A dowel pin 11 is preferably employed to centralize thev parts. A worm 12 having a squared bore 13 open at both ends is supported in matched bearings 14 formed as a part ofthe plates of the base member. The worm 12 has expanded ends 15 so as to prevent dislodgment of the worm. A segmental gear -16 is mounted on the stud shaft 17, suitable anti-friction bearing 18 being interposed between the shaft and the gear. This-gear 16 Vvhas, `a shank 18 which is xedly secured to the larm 4 which arm 4 is preferably composed of sheet metal with the lower edges apart so as to leave a slot or opening 19. The rod 5, corresponding in shape to the arm 4,-isenclosed within the latter, and is larranged to slide therein. At

4the free end of the rod 5, the bracket 6 is connected by pivot pin 7 to said rod. `When the improved device is to be set up 1n .its (position for operation, the base 3 is secure on the window sill adjacent to the window frame in all cases whether or not the window works to thelleft 'or to the right. When, for example, the device is to be used for a window swinging outwardly to the left, the device is in the position shown by Figure 5 with the bracket 6 inthe full line sition but whenthe device is used for a rig t hand swinging window, the bracket is in the broken line posltion and the complete device is turned around so that the oppositeside ofthe base will be the operating side.

In practise, there may -beiconsiderable va-A riation in the ldepth of the window sill, for example, so that an operating crank or key must be provided to meet thevariable condi tions. For this purpoftheextensible operating means shown in Figure 6 may be employed with advan This operating d means consists of a. tu ular hollow head 20 having a uared shank 21 which shank is adapted to received in the squared bore of t e-worm 12 from either end. A handle having the shank 21" fits in the hollow tubular 110 member 20k and by means of set Ascrew 22 and groove 23, said handle maiy be adjusted toand positions.

Various modifications may be made in car- -rying` out the details of the invention hereinbefore described and it is to be understood that any modification coming fairly within the terms of the appended claims shall be covered thereby.

I claimu 1. An operating;y device 0f the class described rendered operative for windows mov- A ing in several or opposite directions by location .of the device, said device havin a body or base, a pivoted arm or outer mem r supported by and swinging` from said base, a rod or inner member slidably mounted with relation tocsaid arm, a pivoted bracketfcarried -dev'ice by location for operating windows Legans at the outer end of said rod and means opera-. tive from either side of said base wherebyl operation of said arm'is effected. i 2. A easement window opera ,device having a base, a pivoted arm extending from said base,l arod telescoping into said arm, a bracket pivotally mounted on the outer end of said rod; a woi'm andsegmental gear for opera said arm and means whereby op. eration o sai'd worm and gear is effected from either side of said base so as to adapt said in opposite directions.
